DSSP-002: Naming Conventions and Labeling Revision 1.6 (05/09/19) John P. Willis Datashed Proprietor ABSTRACT This document details standards for equipment naming and labeling, to be followed in new system or network deployments 1. Naming Conventions 1.1. Network Equipment Network equipment MUST be named according to the following convention: aa-bbbb-nn aa represents one of the following equipment classes: * sw - switch * rt - router * ap - access point * fw - firewall bbbb represents one of the following roles: * core - core * tor - top-of-rack * edge - network edge * acc - access * agg - aggregation * virt - virtual May 9, 2019 - 2 - Finally, nn represents a sequential number from 00-99. Numbers less than 10 MUST be padded with a leading zero. 1.1.1. Naming Exceptions Nonconforming names MUST be allowed in the following cir- cumstances: * Where the nonconforming name has exceptional personal or historical meaning * Where the device being attached cannot, for technical, legal, or contractual reasons, be assigned a conforming name * Where networks connected pursuant to DSSP-008 have a differing set of naming conventions 1.2. Network Hosts Network hosts MUST be named after Greek mythological fig- ures. It is acceptable to provide an alias, e.g. mail, web, nsXX, via local name resolution mechanisms (DNS, WINS, NIS/NIS+, LDAP, etc.) as-needed, as long as the primary hostname fol- lows this standard. 1.2.1. Naming Exceptions Nonconforming names may be allowed in the following cir- cumstances: * Where the nonconforming name has exceptional personal or historical meaning * Where the host being attached cannot, for technical, legal, or contractual reasons, be assigned a conforming name * Where networks connected pursuant to DSSP-008 have a differing set of naming conventions 2. Physical Requirements 2.1. Labeling Labeling of cables MUST follow ANSI/TIA-606-B labeling _________________________ Names that violate DSSP-012 SHALL NOT be allowed on the network, without regard to the usual naming exceptions in DSSP-002.

The following facilities exist: * 1DCA is the datashed itself (1st floor, Data Center A) * 1HTR is the IDF in the house (1st floor, Home, Telecom Room) The following special considerations are to be followed for 1DCA: * Rack numbering begins at C01 (Cabinet 01), the left primary networking rack, and proceeds counter-clockwise around the building. 2.1.1. Remote End Representation The label on the near terminus of a given cable MUST denote the location of the far terminus and vice-versa. 2.1.2. Example Label A label with designation 1DCA.C02-36:1 would be read as fol- lows: * 1DCA represents the floor and building; in this case, "1st floor, data center A" * C02 represents the location within 1DCA (C02 for Cabinet 2). TIA-606-B suggests using grid coordinates denoted by raised floor tiles for this portion of the label, but allows for custom nomenclature in data centers where grid coordinates are not feasible: 1DCA has only five racks, numbered C01 through C05, and no raised floors. * 36 represents the location at which the equipment is installed within the rack or enclosure, as numbers of rack units from the floor (i.e., the lowest position in the rack is 01, and the number increases as you move towards the ceiling). Note that in cases where a piece of equipment occupies more than a single rack unit, the number is the upper- most rack position occupied by the equipment in ques- tion. * 1 represents a 1-based port number on the equipment.
